Background
- After failure to control the airway, blunt abdominal
trauma (BAT) is the second most frequent cause of preventable death in pediatric trauma patients
- Evaluation of pediatric BAT can be challenging
- External signs may be few
- Physical examination can be unreliable
- CT is over-utilized and poses radiation risk

Background
- Young level I trauma center
(certified in 2010)
- Large institution: multiple EM
and Surgery providers leads to variability in evaluation/management
- New protocol in Aug 2011 –
primary evaluation level 2 activations by EM staff; trauma surgeon consulted
- nly when necessary

Objectives
- QI project: Development of an evidence-based
protocol to evaluate abdominal trauma in EC
- To standardize care among multiple providers
- To ensure appropriate and timely surgery consultation
- To decrease unnecessary CT and lab use in evaluation of
abdominal trauma
- To maintain or improve safety and quality of care of
trauma patients

Protocol Deviation
- Some step of the protocol was not followed 30% of the
- time. Most common:
- CT based on mechanism alone
- CT before surgeon evaluation most common
- 46 CT scans (36%) may have been avoided if protocol
had been followed
- Clinically significant CT scans when protocol followed =
43% vs. 11% when not followed (p = 0.001)

Conclusion
- An institutional protocol to streamline evaluation of
children with suspected blunt abdominal trauma was effective in decreasing unnecessary CT use and laboratory costs
- Future directions include further protocol refinement
to decrease the role of CT in the evaluation algorithm
